This paper describes a lumped analytical model of liquid-anode single-tube and vapor-anode multi-tube AMTEC cells. The model results agreed well with experimental data for Mo, NbN and TiN electrodes. Results showed that Mo and NbN electrodes exhibit high B values between 400 and 600 A.K1/2/Pa.m2, and have the potential for peak power densities slightly above 1 W/cm2, with efficiencies as high as 28%. In contrast, TiN electrodes have lower temperature-independent exchange currents, between 120 and 135 A.K1/2/Pa.m2, lower peak power densities between 0.5 and 0.75 W/cm2, and efficiencies below 24% at a BASE temperature of 1200 K. These values of B compare well with that reported by other investigators.
